The advantages of metal shims
Metal shims can be manufactured from a variety of metals and finishes, including mild steel, galvanised steel and stainless steel. Metal shims are strong, durable and offer some resistance to corrosion, being suitable for industrial applications.
What is a metal shim?
In general, a shim is a piece of material used to fill gaps, offer extra support and level surfaces. Also known as a spacer or packer, shims are versatile and can be used for a variety of applications. As the name suggests, metal shims are constructed from metal and have the same purpose as other types of shims.

What are shims made of?
There are various types of packers and shims available, from plastic shims and metal shims to hi-load shims. Hi-load shims are manufactured from polycarbonate and polyamide, which have higher strength than regular polypropylene and polystyrene. Hi-load shims are a cost-effective alternative to the heavier steel shims.
What are metal shims used for?
As metal shims are stronger than standard plastic shims, these can be used for a wide range of purposes, from general use to heavy industrial applications. This includes aligning packaging and production equipment, aligning pipes, adjusting the clearance levels of two objects and more.

Some metal shims, such as stainless steel shims, are also resistant to corrosion, being suitable to be used in the petrochemical and pharmaceutical industries or any other industries that require shims to withstand high temperatures and stress.
